AB: Two eruptive flares that occurred on 17 December 2006 and 19 May 2007 were observed by the instruments on the Hinode and RHESSI spacecraft. Both share some of the characteristics of the well known event observed with Yohkoh in February, 1992 (Tsuneta et al., 1992) in that they seem largely thermal in character and exhibit many of the features of the standard Carmichael, Hirayama, Sturrock, Kopp, Pneuman (CHSKP) flare model. However for these events, much additional (e.g. SOHO) data is available including the observation of an associated erupting filament on 19th May that was seen at the Kanzelhoehe Solar Observatory. In this talk the role of the outflow termination shock in heating the flare plasma will be re-examined. In particular the presence of plasma over a wide temperature range in the flare cusps and the possibility of non-thermal effects following the shock heating, will be assessed. The behaviour of the erupting filament material will also be discussed.
